Water Well Electrical Controls & Control Boxes
Diagnostic testing and replacement of pump control boxes, start/run capacitors, relays, lightning arrestors, and phase monitors.
Common Signs & Symptoms of Failure
- ⚠ Control box emits a loud humming or buzzing sound without pumping water
- ⚠ Burn marks, swollen capacitors, or chemical odor inside the control panel
- ⚠ Frequent tripped pump circuit breaker at the main electrical panel
- ⚠ Pump stopped working immediately following a West Texas thunderstorm
- ⚠ Single-phasing or voltage drop issues on 3-phase ranch electric lines

Our Step-by-Step Field Process
1. Capacitor Microfarad Verification
We discharge capacitors safely and test capacitance rating against factory microfarad (uF) tolerances. Swollen or weak capacitors are isolated and replaced.
2. Potential Relay Diagnostic
We measure coil resistance and verify that the relay properly drops the start winding out of the circuit within milliseconds once the downhole motor reaches 80% speed.
3. Voltage Drop & Amperage Load Analysis
We test incoming supply voltage under start-up and running load. We check for voltage sag over long rural electric co-op lines that could starve the pump motor.
4. Industrial Surge Protection Installation
We wire commercial metal oxide varistor (MOV) lightning arrestors directly to the incoming service line and connect robust copper earth grounding rods.
Edwards Aquifer & West Texas Geology
Lightning strikes across open Val Verde pastures and Amistad basin flatlands create destructive voltage spikes on rural electric co-op lines. Every system we service is outfitted with commercial-grade surge arrestors to shield expensive downhole equipment.
Preventative Maintenance Tip for Landowners
After every severe lightning storm, visually check your control box for discoloration or a sweet, pungent smell indicating an exploded electrolytic capacitor.
Frequently Asked Questions
Can I replace just the capacitor instead of the entire control box?
Yes. In many cases, only the start capacitor or potential relay has failed. We test every component individually with calibrated multimeters and replace only what is damaged to keep repair costs fair.
Do 2-wire pumps have a control box?
No. 2-wire pumps have all starting electronics built into the motor underground. 3-wire pumps have a surface control box mounted on the wall, making electrical diagnosis and component replacement fast without pulling the pump.
